Cocaine 'rapidly changes the brain'

Cocaine 'rapidly changes the brain'

Brain cells 
 
 The researchers looked for tiny protrusions from brain cells called dendritic spines

Taking cocaine can change the structure of the brain within hours in what could be the first steps of drug addiction, according to US researchers.
Animal tests, reported in the journal Nature Neuroscience, showed new structures linked to learning and memory began to grow soon after the drug was taken.
Mice with the most brain changes showed a greater preference for cocaine.
Experts described it as the brain "learning addiction".
The team at University of California, Berkeley and UC San Francisco looked for tiny protrusions from brain cells called dendritic spines. They are heavily implicated in memory formation.
Cocaine hunting The place or environment that drugs are taken plays an important role in addiction.
This study gives us a solid understanding of how addiction occurs - it shows us how addiction is learned by the brain”
Dr Gerome Breen Institute of Psychiatry
In the experiments, the mice were allowed to explore freely two very different chambers - each with a different smell and surface texture.
Once they had picked a favourite they were injected with cocaine in the other chamber.
A type of laser microscopy was used to look inside the brains of living mice to hunt for the dendritic spines.
More new spines were produced when the mice were injected with cocaine than with water, suggesting new memories being formed around drug use.
The difference could be detected two hours after the first dose.
Researcher Linda Wilbrecht, assistant professor of psychology and neuroscience at UC Berkeley, said: "Our images provide clear evidence that cocaine induces rapid gains in new spines, and the more spines the mice gain, the more they show they learned about the drug.
"This gives us a possible mechanism for how drug use fuels further drug-seeking behaviour.
"These drug-induced changes in the brain may explain how drug-related cues come to dominate decision making in a human drug user."
Commenting on the research, Dr Gerome Breen, from the Institute of Psychiatry at King's College London, told the BBC: "Dendritic spine development is particularly important in learning and memory.
"This study gives us a solid understanding of how addiction occurs - it shows us how addiction is learned by the brain.
"But it is not immediately apparent how useful this would be in developing a therapy."

Russia's Arctic: Mission to protect wildlife

Russia is planning huge oil and gas developments in the Arctic Ocean off its northern coast - drilling that could threaten pristine wildlife habitats.
Large-scale production could begin in the next two decades, if the price of oil rises high enough.
Preliminary exploration has already begun, including in the Laptev Sea.
But scientists say the region is home to important, thriving populations of walrus and polar bears, which could be put at risk.

The early retreat of ice makes life harder for the polar bear and walrus
Biologists on the 2013 Laptev Expedition this summer have been trying to establish if the walruses and polar bears there are a unique group, in need of special protection. BBC journalists went with them to investigate the issue.
We flew to Khatanga, one of the most northerly towns in Siberia, and there we boarded a small boat, the Taimyr.
From Khatanga it was a two-day, 500km (310-mile) journey almost due north.
Polar bears After the first day it became clear we had entered the domain of the polar bear. First we saw a mother with two five-month-old cubs on Maliy Begichev Island.
Then we saw a big "haul-out" of walrus at Cape Tsvetkov - perhaps 400-600 there, resting on the beach. Towering above them on the last large lump of ice was a large polar bear.
But our destination was Maria Pronchishcheva Bay, half-way up the Taimyr Peninsula. It is the most northerly bit of land in the world still attached to a continent.
"The oil companies are coming here with exploration projects already, and there are ongoing seismic explorations," said Igor Chestin, chief executive of the environmental group WWF Russia.
"So before the real oil and gas projects develop in the area we need to know that there is sufficient knowledge of the conservation needs here, which would allow us to put in the necessary protection if this development ever happens."
From satellite photographs taken a week earlier, the scientists on the expedition knew there had also been a large walrus "haul-out" there previously. By the time we sailed into the bay the number had dropped to around 60. But it was still enough for the crucial scientific work of the expedition - collecting DNA from the Laptev walrus.

Researchers want to find out more about the Laptev walrus
Collecting samples Walrus expert Anatoly Kochnev of ChukotTINRO, a marine biology group, was despatched to the pebbly spit where the animals were resting.
We watched as he fired crossbow darts into the sides of the walrus, which he then retrieved with a thin piece of line attached to each dart. At the head of each dart was a biopsy punch, which pulled out a piece of walrus skin and fat as it was retrieved.
The samples will be sent to labs in Moscow and Denmark for DNA analysis. The plan is to end a long scientific dispute over whether the Laptev walrus is a unique sub-species in need of special protection, genetically different from the Pacific walrus and the Atlantic walrus.

Just one hour after Anatoly Kochnev's third trip out to the spit, a huge male polar bear appeared in the exact spot where he had been kneeling to fire the crossbow. The bear tried to kill one of the walrus, but was unsuccessful - this time.
Polar bear expert Geoff York of WWF's Global Arctic Programme is collecting samples - faeces and hair - which will also be sent for DNA analysis. Again there is a concern that the polar bears of the Laptev Sea may be unique and in need of special protection.
"If that is true then in most countries you would need to identify the habitat being used by bears," Geoff York said.
"Are they making dens onshore? How are they using the land in summer? Then you would protect those habitats at least in the relevant seasons. If you do indeed have two unique sub-populations of marine mammals here you might consider that this should be a Marine Protected Area, and you might exclude any industrial development."

Ice retreating
The concern about the large marine mammals of the Laptev Sea has increased in the last decade for two reasons.
Firstly, climate change has led to a dramatic shrinking of the Arctic ice cap in recent summers. This has meant that in order to stay close to their feeding grounds the walruses have had to come ashore in much larger numbers, instead of staying on the ice where they feel more comfortable.
Polar bears are also being forced ashore, where they find it much harder to feed. Their preferred meal, the ringed seal, is not available onshore and they often are reduced to going after the much more dangerous walrus.
Secondly, there are plans to develop the Laptev Sea for oil and gas production. The water here is shallow, which makes it easier to drill, and there are believed to be large deposits of hydrocarbons. This exploration work may frighten the nervous bear and walruses, and could disrupt their food supply.
Conservationists think the arrival of much greater numbers of humans could also increase hunting, further disrupting the delicate balance of nature here. They say that nobody has yet worked out how to control an oil spill in seas that are close to freezing.

The Russian government says the country's future wealth depends on exploiting the deposits here and in other parts of the Arctic. The deposits will not be easy to extract, but they are almost certainly there.
"Most of the estimates give more than 20% of global undiscovered oil deposits to Russian Arctic seas," said Alexev Piskarev, author of Energy Potential of the Russian Arctic Seas.
Shipping route The melting sea ice has also opened up new shipping routes. Russia is now advertising the Northern Sea Route, which cuts the journey time from China to Europe by up to two weeks.
"You save time and you save fuel. It is much more economical," said Alexander Olshevsky, head of the Northern Sea Route Administration. "Though you will need to pay for a nuclear-powered icebreaker, and of course you will need a boat that can deal with these conditions."
But again, opening up the Northern Sea Route could disrupt the fragile ecosystem. More than 400 ships will make the journey this year - yet in 2010 it was only four.
On our brief, two-week trip we have seen extraordinary fire-red Arctic skies, gleaming snowy owls and grumpy musk ox, and an almost untouched landscape of thin yellow tundra covering the permafrost. The temperature has barely risen above 10C and has often been closer to freezing.
It is one of the last wildernesses of the world, a place few people even know exists, but modern industry is already starting to encroach on it.

Syria crisis: UN inspectors' convoy 'hit by sniper fire'

Syria crisis: UN inspectors' convoy 'hit by sniper fire'


The BBC's Yolande Knell: "The UN has always said the safety of its team is paramount"
Unidentified snipers have opened fire on a convoy of UN experts investigating suspected chemical weapons attacks in Syria's capital, the UN has said.
One car was shot at "multiple times", forcing the convoy to turn back. The UN promised to continue with the inquiry as soon as it could replace the car.
Syrian state media blamed opposition "terrorists" for the attack, though the claim could not be verified.
Hundreds died in suspected chemical attacks on Wednesday near Damascus.
The US said there was little doubt Syrian forces used chemical weapons in the attacks, which reportedly killed more than 300 people in rebel-held areas.
Syrian President Bashar al-Assad dismissed the accusation as "an insult to common sense" and warned the US against military intervention.
"If someone is dreaming of making Syria a puppet of the West, then this will not happen," he told the Russian newspaper Izvestiya.
Intimidation
The 20-member UN inspection team has been in Syria since 18 August to look into three earlier suspected chemical attacks.
The experts intend to take soil, blood, urine and tissue samples for laboratory testing from five locations on Monday and Tuesday.
They were unlikely to play any role in apportioning blame for the attack.
But shortly after setting out from the hotel, the cars came under fire "multiple times by unidentified snipers", according to a statement from the UN.
"The team returned safely back to the government checkpoint. The team will return to the area after replacing the vehicle," said the UN.
The UN Secretary General's spokesman, Farhan Haq, told the BBC the convoy was "deliberately targeted" but those behind the shooting remain "unidentified at this stage".
He said that it seemed someone was trying to intimidate the team.
Military action A year ago, US President Barack Obama said the use of chemical weapons by the Syrian government would be "a red line" that could trigger US military action.
Washington has recently bolstered its naval presence in the eastern Mediterranean, and military leaders from the US, UK and their allies are meeting in Jordan.
But the UN Security Council remains divided, with China and Russia appearing unlikely to drop their objection to stricter sanctions on Mr Assad's government.
Chinese Foreign Minister Wang Yi said on Monday that diplomats should be cautious in dealing with the chemical weapons issue, and Moscow warned Western nations not to prejudge the outcome of the inspections.
Western politicians have begun to suggest taking action outside of the UN system.
UK Foreign Secretary William Hague told the BBC that action could be taken without UN approval if there was "great humanitarian need" in Syria.
Hans Blix: "It's important that [the inspectors] can go to any place they want to see"
His French counterpart Laurent Fabius suggested the UN Security Council could be bypassed "in certain circumstances".
Turkish Foreign Minister Ahmet Davutoglu told the Milliyet newspaper that more than 30 countries were already discussing how to act on Syria if the UN failed to agree.
He promised that Turkey would join any coalition against Mr Assad's government, with or without UN backing.
'Neurotoxic symptoms' Western officials were unimpressed with Syria's decision to allow in the UN experts.
Mr Hague said evidence could have been tampered with, degraded or destroyed in the five days since the attack.
A senior White House official, quoted by AP news agency, dismissed the visit as "too late to be credible".
Medecins Sans Frontieres (MSF) said on Saturday that three hospitals it supports in the Damascus area had treated about 3,600 patients with "neurotoxic symptoms" on Wednesday morning, of whom 355 died.
While MSF said it could not "scientifically confirm" the use of chemical weapons, staff at the hospitals described a large number of patients arriving in the space of less than three hours with symptoms including convulsions, pinpoint pupils and breathing problems.
Syria's security forces are widely believed to possess large undeclared stockpiles of mustard gas and sarin nerve agent.
It is one of seven countries that have not joined the 1997 convention banning chemical weapons.

Warning Over £100,000 Charity Executive Wages


Warning Over £100,000 Charity Executive Wages

There are fears six figure salaries for staff at 30 UK charities could discourage people from continuing to make donations.

Six figure salaries for staff at Britain's taxpayer-funded foreign aid charities risk bringing the industry into disrepute, the Charity Commission's chairman William Shawcross has warned.
Some 30 people working at the 14 leading UK charities that make up the 50-year old Disasters Emergency Committee (DEC) are paid more than £100,000 a year, according to new figures.
A Daily Telegraph investigation into charity industry salaries showed British Red Cross CEO Sir Nick Young earns £184,000 a year.
James Forsyth, chief executive of Save the Children, earns £163,000, while the charity's chief operating officer Anabel Hoult earns £168,653.

William Shawcross says some salaries will not seem fair to donors
Mr Shawcross told the Daily Telegraph: "It is not for the commission to tell charities how much they should pay their executives. That is a matter for their trustees.
"However, in these difficult times, when many charities are experiencing shortfalls, trustees should consider whether very high salaries are really appropriate, and fair to both the donors and the taxpayers who fund charities.
"Disproportionate salaries risk bringing organisations and the wider charitable world into disrepute."
Three years ago, 19 staff members at the DEC charities, which are mandated to raise funds quickly for crisis-struck parts of the world, earned more than £100,000.
DEC says it has run 62 appeals and raised more than £1.1bn since launching in 1963.
The charities involved with DEC include Action Aid, Age International, British Red Cross, CAFOD, Care International, Christian Aid, Concern Worldwide, Islamic Relief, Merlin, Oxfam, Plan UK, Save the Children, Tearfund and World Vision.
Sir Stephen Bubb, chief executive of charity leaders organisation Acevo, said the intervention by Mr Shawcross was "deeply unhelpful".
The average salary for a charity chief executive was £58,000, he said and added: "The big national and international charities are very demanding jobs and we need to attract the best talent to those jobs and that's what we do."
Sir Stephen denied that the high salaries could put off donors.
He said: "This simply isn't an issue for donors. Donors are more concerned about the outcomes, the performance and the efficiency of these organisations.
"To keep talent, really strong people, at the top of these organisations they need to be paid properly. These are still not excessive salaries when you compare them to the public and private sectors."

Dreamliner Grounding 'Cost Carrier ANA £53m'

Dreamliner Grounding 'Cost Carrier ANA £53m'

An ANA's Boeing Co's 787 Dreamliner plane receives restoration work at Okayama airport in Okayama, JapanAs All Nippon Air hits turbulence because of rising fuel prices, it reveals the grounding of its Boeing 787 fleet cost it £53m.

 

Japan's All Nippon Airways (ANA) has said the grounding of its Boeing Dreamliner fleet has cost it 8bn yen (£53m).
The announcement comes after the carrier made a second-quarter loss of 6.6bn yen (£44m).
It reversed a small year-earlier profit, despite a 4.4% rise in revenue to 358.3bn yen (£2.38bn).
"The primary reason for the increase in operating expenses was a rise in fuel costs due to the weakening of the yen," it said in a statement.
"Operating revenues were also held back by the suspension of Boeing 787 services for part of the period."

ANA and domestic rival Japan Airlines, which reports its quarterly results Wednesday, were sideswiped by the grounding of Boeing's new aircraft that began in January.
After a long-running probe the planes were allowed to fly again in June.
The carriers at the time operated about half the Dreamliners in service and had to cancel hundreds of flights in the wake of the crisis, which was caused by problems with the plane's lithium battery.
The carrier and Japan Airlines have said they will seek compensation from Boeing having lost a combined total of more than 22.5bn yen (£149m) in revenue.

The fire at Heathrow was suspected to have been caused by a beacon battery
"The impact of the problems was bigger than originally expected," Kei Yamamura, an aviation analyst with SMBC Friend Securities, said.
"But this factor will fade toward the end of the fiscal year as long as these issues don't come up again."
Although issues related to the auxiliary power supply lithium battery appear to have been resolved, emergency locator transmitters (ELT) used by Boeing now appear to be under scrutiny.
A fuselage fire on an Ethiopian Airways 787 at Heathrow airport on July 12 was pinpointed to the ELT manufactured by Honeywell.
The US Federal Aviation Administration advised on the emergency beacon wiring being checked.
Boeing has subsequently told airlines up to 1,200 aircraft across a range of models have the ELTs fitted.
